[QUOTE="Son of Butch, post: 1535177, member: 14585"] The reason why Wagyu cattle can score higher than usda high prime and other breeds don't is in how they marble. It has been linked to an unique DNA sequence of the SCD gene which changes stearic acid to oleic acid. The SCD gene with an amino acid mutation from valine (type V) to alanine (type A) is responsible for the softer fat with a lower melting point which is the key to the flavor profile of Wagyu beef. Wagyu beef has a 2:1 ratio of monounsaturated to saturated fatty acids which is the reverse of conventional beef. Not all Wagyu cattle carry 2 copies of the SCD AA gene, but identifying those that do and using them as breeding stock should ensure the most marbling when crossbreeding. The AA gene correlates most often with the Tajima bloodline. To answer your question, you can't get Wagyu semen from Japanese sires and your best bet would be to locate semen from Wagyu full blood sires born outside of Japan and tested AA The highest ranking is AA 10 Takamichi Doi - AA 8 I've been doing a little crossbreeding with Wagyu and have few a Takamichi Doi heifers. I bought the semen from Baycroft Wagyu Baycroft has semen available on a young sire named Bay Ito Macho... he is AA 10 for SCD and Tenderness [url=http://www.baywagyu.com/AboutOurHerd-Macho.html]http://www.baywagyu.com/AboutOurHerd-Macho.html[/url] This year I used a couple Wagyu sires from Origen ...
